1
Legato phrasing on a synthesizer
is usually achieved by playing overlapping notes
is usually achieved by holding down the sustain pedal
is not possible-only samplers offer a legato option
2
White & Pink noise
are random signals that can be used as sound sources or modulators
are filters that can be used to add color to various sound sources
are digital processes that are available in modern synthesizers
3
A sampler that uses keyswitching
can be locked onstage so others cannot play it
selects different sampled articulations of an instrument from different keys
can automatically transpose an instrument by playing in a different key
4
An analog synthesizer
uses a chain of one-cycle samples to create its complex sounds
uses oscillators and filters to shape its sounds
uses samples recorded on analog tape as its sound sources
5
VCA stands for
Voltage-Controlled Amplifier
Voltage-Controlled Activator
Video-Cassette amplifier
6
A multi-timbral instrument
can play multiple instruments at the same time
is polyphonic-that's what multi-timbral means
includes an EQ for multiple timbres for its single instrument
7
Multi-sampling
means that the sampler has many different sampled instruments to choose from
means that the sampler is polyphonic
uses many samples from the same source to minimize sample transposition
8
In a sampler Transposition
is automatically done to all samples within a user-specified range
morphs between two different instruments loaded simultaneously
automatically matches each sampled instrument to the key of a particular song
9
Sequential Circuit's Prophet 5
used digital sound sources to create its sounds
included 5 stackable oscillators for a rich sound
was one of the first synths to have patch memories
10
Time-shifting in a sampler instrument
allows for greater flexibilty when working with sampled loops
automatically transposes the instrument to match the key of the current song
automatically corrects the pitches in vocal samples
11
Additive synthesis
layers a collection of bright analog oscillator waves for a rich sound
creates a complex sound from a chain of short one-cycle samples
builds up a complex wave from individually assembled sine wave harmonics
12
Modern sample libraries
are smaller than ever, due to modern efficiencies
often utilize hundreds of samples for greater realism
still utilize 8-bit resolution for efficiency
13
What analog synthesizer brand is famous for its 4-pole lowpass filter?
Moog
Buchla
ARP
14
Pusle Width Modulation (PWM)
allows for dynamically changing the shape of a pulse wave via LFOs or EGs for timbral variations
is only possible on modular synths
is only available on digital emulations of analog synths
15
A Sampler
uses recordings of notes or sounds as its sound source
is a mixtape with snippets of various songs
uses digital oscillators to create buzzy waveforms
16
In FM synthesis a Carrier-Modulator pair
is a combined lowpass & highpass filter used to create richer tones
is a pair of (usually) sine wave oscillators that use FM to create rich tones
takes the place of a filter and amplifier EG
17
The East Coast & West Coast schools of synthesis
tend to use all-digital vs all-analog technologies, respectively
both incorporate all-digital technologies
generally follow the design philosophies of Moog vs Buchla, respectively
18
In an analog synth Vibrato can be created
by patching an LFO into a VCO
by patching an LFO into a VCA
by patching an LFO into a VCF
19
The earliest samplers
had a gritty sound due to their 8-bit resolution
had only 24-bit resolution instead of the 48-bit resolution of modern samplers
were all virtual instruments
20
In a sampler Velocity Zones
utilize multiple samples of the same note at different dynamic levels
utilize multiple samples of the same note on different keys
are very fast sequences of notes
21
The stages of a typical 4-stage ADSR Envelope Generator are
Activation, Dynamics, Saturation, Release
Attack, Decay, Sustain, Release
Amplifier, Dropoff, Sustainer, Regulator
22
In traditional analog synths the most common type of VCF is
a lowpass filter
a spectral filter
a notch filter
23
To create a percussive envelope with an ADSR envelope generator
Decay & Release would be set to their fastest values
Sustain would be set to zero
Attack would be set to its slowest value
24
The Yamaha DX7
sounded good but was a failure in the synth marketplace
mixed analog oscillators with digital processing
had pairs of sine wars that used FM synthesis to create its sounds
25
Synthesizer parameters
are all always preset to their optimal settings to ensure the best sounds
are the adjustable controls used to shape sounds
are the dimensions of the synthesizer's case
